COVID19_Vaccine_Weekly

0. Coverage: booster

0.1. Number of people eligible for booster

As of October 24, 2021,

FDA authorization
“The use of a single booster dose of the Jansen (Johnson and Johnson) COVID-19 Vaccine may be administered at least 2 months after completion of the single-dose primary regimen to individuals 18 years of age and older.”

CDC’s guidelines:
“For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at 6 months or more after their initial series: - 65 years and older
- Age 18+ who live in long-term care settings
- Age 18+ who have underlying medical conditions
- Age 18+ who work or live in high-risk settings”

As of 2021-11-02, 42179 county residents are officially eligible for the booster shot - simply based on the type and timing of vaccines they received earlier. Below figure shows projected number of people who would have become eligible for a booster based on their age and manufacture of their first vaccine (6 months after their second shot for PFR and MOD; and 2 months after their first shot for JSN).

0.2. What is the weekly pace of booster shot vaccination?

Using the Immunet data, a booster shot is defined using the following.
- 3rd or higher order shot for those who received PFR/MOD vaccines for their first shot AND the interval is 120 days or longer from the previous shot.
- 2nd or higher order shot for those who received JSN vaccines for their first shot AND the interval is 60 days or longer from the previous shot.

See Annex 2 for more about how to define a booster shot

As of 2021-11-02, a total of 16438 “booster” shots were given.
* In the last 7 days, 5850 booster shots were provided, compared to 2915 in the week before.

0.2.1. Weekly number of booster shots

Trend of booster shots by eligibility status - simply based on the age and manufacturer of their initial shot.

0.2.2. Weekly number of booster shots by time since previous shot

0.2.3. Weekly number of booster shots by age group

Majority of them were given to people 60 and older, there are younger people who also preemptively got booster shot(s).

0.2.4. Weekly number of booster shots by type of place

Pharmacies are main source for booster shots. In the last two weeks, there were 8765 booster shots were provided, 90% among them were given at pharmacies and 0% were given at hospitals.

0.2.5. Weekly number of booster shots by manufacturer of the booster shot

0.3. Among those who are eligible, who is getting the booster shot?

* Simply based on the age, type and date of the initial shot, a total of 10283 shots were given to people who were eligible to receive a booster. This is 24 % of the total 42179 eligible people for booster to date.
* Booster rate varies by background characteristics:

The breakdown by both manufacturer and race suggests that booster rates are lower among Hispanic and Black groups.

Annex 1: Description of the data

Population data
- Population (total and by age and race) come from 2019 population estimates in “County Population by Characteristics: 2010-2019”: https://www.census.gov/data/tables/time-series/demo/popest/2010s-counties-detail.html.
- Population by ZCTAs come from the county government, including adjusted population in five double-county areas.

Vaccination data - The data are at the vaccination case-level, and include vaccinations either administered in Harford County (regardless of residence of people) or vaccinations of Harford County residents (regardless of place of administration). As of May 3, 2021, the daily data include only vaccinations on March 1 or later. Thus, older vaccinations are from the previous update on April 30, 2021.
- There are a total of 377566 vaccinations administered to 198604 people.
- A total of 64725 vaccinations were administered at the HCHD clinic, regardless of clients’ county of residence. 83% of vaccinations were for the county residents.
- A majority of vaccinations (84%) are for the county residents: 318079 vaccinations administered to 162803 people, including 160391 people living in the 17 zip code areas. All analysis in this site is restricted to the county residents.
- 42% of vaccinations for the county residents occur outside the county.
- Vaccination date ranges from 2020-12-16 to 2021-10-31.
- Age is age as of January 14, 2021, to avoid rolling changes in denominators.

Data quality check: Number of vaccinations with missing entry or likely errors
- Missing age:7
- Missing sex:0
- Missing race or ethnicity:0
- Likely errors in vaccine date-person link (i.e., total number of vaccinations >= 3): 16857
- Likely errors in vaccine date (i.e., vaccine date < 12/14/2020): 3
- Likely errors in giving unique CLIENT_ID (i.e., very likely one person getting two ID, based on DOB, sex, last name, and street address): 382

Annex 2: How to define a booster shot from the Immunet data

Given the number of vaccinations per person in the dataset (see the first table below) and even some variation in the type of vaccines within a person (see the second tabulation), it is not necessary straight forward to identify a (new) booster shot.
